Answer to Question #58537 in Statistics and Probability for Melody

Question

If p(A)=0.5, p(B) = 0.25, and A and B are independent.

- what is value of p(A&B)?

- what is value of p(A|B)?


Notes:
A & B are independent if P(A) = P(A|B)
When A & B are independent, then P(A&B) = P(A) x P(B)

P(A or B) = P(A) + P(B) - p(A+B)
